About these units
Barrel (Oil) (bbl (oil))
An oil barrel is defined as 42 US gallons, or 158.987 liters, and is a fundamental unit in the petroleum industry. This peculiar size traces back to the early Pennsylvania oil fields, where producers standardized whiskey barrels and modified wooden casks for oil transport. The need for consistent trade volumes cemented the 42-gallon barrel as the industry norm. Today, global oil production, pricing, and consumption are expressed in barrels—from daily OPEC reports to energy market forecasts. Even though oil is no longer physically shipped in barrels, the unit remains deeply embedded in international energy economics.
CCF (ccf)
The abbreviation CCF stands for centum cubic feet, meaning 100 cubic feet. It is widely used by water and natural gas utilities to measure residential and industrial consumption. Water bills in many US cities list usage in CCF, balancing numerical convenience with practical scale. For example, a household may consume 5–12 CCF per month, depending on climate and household size. Because natural gas companies also use CCF, the unit plays a central role in energy billing, conservation programs, and environmental reporting. It is a key bridge between technical engineering measurements and everyday consumer usage.
